Configure the number of retries for
gethostbyname() and gethostbyaddr()
Independent of whether name server caching is enabled or disabled, the Windows API functions
gethostbyname() and
gethostbyaddr() will be used at some points. Under
certain conditions (network problem, DNS problems) these calls
might fail. This would then be interpreted as "node name could not
be resolved". There is however a very low probability that a name
or IP address could be successfully resolved if these calls would
be retried more often.
By default, the maximum number of retries is 3. So if the first call fails, there is a maximum of 2 more retries. Such retries however have a significant impact on the time it takes to decide whether a node name is resolvable or not. If the assumption can be made that the network and DNS is reliable and is properly configured, then the number of retries can be set to the minimum value of 1. In case there are some doubts on the reliability of the network and DNS, the number should be set to 2 or 3.
The number of overall retries for the Windows API calls
gethostbyname() and gethostbyaddr() is configured by
the value Name resolution retries in the Node Cache
Settings namespace in the Server Configuration dialog box.
After you have changed a value, restart the OvEpMessageActionServer
service for the change to take effect.
| Value | Value Range | Effect |
| Name resolution retries | 1-3 | Specifies the maximum number of retries in case of
unsuccessful gethostbyname() and
gethostbyaddr() function calls.
Default value=3 |
